Most analyses and reviews of utility-scale, highly intermittent new renewables, especially wind power which will be the focus here, are lacking in perspective. This makes marginal aspects appear to have significance out of proportion to the very little value they represent.
A few examples are:
· A focus on the energy contribution (MWh) from wind power leads to error in assessing the contribution to electricity costs, reliability, impact on fossil fuel consumption and CO2 emissions, transmission needs and the operation of an electricity system.
· The possibility of some improvements in wind forecasting. Given the current state of weather forecasting in general, it seems difficult to believe that wind can be forecast for short time intervals, say 24 hours in advance. In any event, even if such forecasting was possible, it does not change the need for balancing generation plants to be ramped frequently to mirror wind conditions.
